1, Jiaren brand shock absorber can suppress the oscillation peak of * * * vibration frequency, reduce vibration transmission along the structure and reduce structural noise. The vibration reduction characteristics of constant shock absorber are poor, and the actual effect of high frequency vibration reduction is poor
2. The permanent shock absorber belongs to this small brand of shock absorber. Jiaren brand shock absorber is very famous in the field of modification. Jiaren brand shock absorber is very good. Automobile shock absorption is very important for automobiles, and shock absorption can improve the performance of wheels on the ground.
